    Abstract: The present invention provides a data packet routing method and device. When a Switch receives, form an SE, a traffic flow on which service processing is performed, the Switch can determine a forwarding rule of a corresponding service chain according to the traffic flow received from the SE, and route, according to the forwarding rule, a data packet received from the SE. Compared with a case in the prior art in which an SPC needs to deliver a forwarding rule corresponding to each traffic flow to a Switch, the embodiments of the present invention adopt the technical solutions in which the SPC only needs to deliver a forwarding rule corresponding to each service chain to the Switch, thereby reducing signaling interaction between the SPC and the Switch and saving a network overhead.

    Abstract: The present invention provides a service routing system, device, and method. In embodiments of the present invention, a first service flow classifier generates a notification message that includes service flow category information, a service path controller generates, according to the notification message, a first forwarding entry corresponding to each of i programmable switches that are connected to k service enablers, and the i programmable switches each forward a data packet of a service flow according to the corresponding first forwarding entries, so that the k service enablers process the data packet of the service flow according to a sequence. In this way, network reliability can be improved.

    Abstract: A method for user detachment when a handover or change occurs in a heterogeneous network is provided. The method includes: a user equipment (UE) is handed over or switched from a source network to a target network; a network element on a network side determines whether to detach the UE from the source network, and if yes, the network element on the network side detaches the UE from the source network. A system and a device for user detachment when a handover or change occurs in a heterogeneous network, and another method for user detachment when a handover or change occurs in a heterogeneous network are also provided.

    Abstract: Method, apparatus and communication system for resource release controlling are provided in the disclosure. When a user equipment (UE) with an idle mode signaling reduction (ISR) being activated moves from a first source network to a second target network, if a first SGSN in the first source network knows that a second SGSN in the second target network does not support interaction with a serving gateway (S-GW) and does not support ISR, the first SGSN controls the deletion of bearer resources on a MME in the first network by sending a resource deletion message.
